10 Dinars 2005 Coup d'état 18th Anniversary, Arabic legend

The "coup d'état" in question is the November 7, 1987 removal of Habib Bourguiba by Prime Minister Zine El Abidine Ben Ali, who declared the founding president medically unfit to govern. Ben Ali then institutionalized the date as a national celebration — "Fête du Changement" — issuing commemorative coinage on each anniversary throughout his presidency. By 2005, eighteen years in, the series had become a reliable fixture of Tunisian numismatic output, one that effectively ended when Ben Ali himself fled to Saudi Arabia during the 2011 revolution.
